DEVICE FOR FEEDING AND CUTTING $OLDER.

SIPECIFICATION forming part of Letters Patent No. 398,665, dated February 26, 1889. Application filed September 5, 1888. Serial No. 284,604. (No model.)

To all '1/710111/ it may concern.- 7

Be it known that; 1, CHARLES W. sLEErEn, a citizen of the United States, residing at Island Pond,in the county of Essex and State i of Vermont, have invented a new and useful Device for Feeding and Cutting Solder, of which the following is a specification.

My invention relates to improvements in feeding and cutting solder for seaming-machines, and is designed to feed automatically from a roll of solder (substantially the width of the scam to be soldered and of any. convenient. thickness) the exact amount of solder required and to drop it upon the seam to be soldered. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which similar-letters refer to similar parts throughout the several views.

Figure 1 is a side elevation of the device, showing a portion only of standard 0 and arm 1'). Fig. 2 is a vertical section of same, taken at line at .r, Fig. 3. Fig. 3 is a plan of the device with the roll of solder E and carrier-roll at removed.

My invention consists of a bed-piece, A, to which are secured two side plates, B B, in

which are bearings for two feed-rolls, a a a carrier-roll, a, and a rolling cutter, a. Two pressurescrews, a a are provided for adjusting the upper feed-roll, a Slots E are provided to receive an d guide the pin E',whieh passes through the center of the roll of solder, E. A steel knife or cutting-plate, u, is secured to the bed A, and an opening, a, is provided for the escape of the solder after being cut off from the roll E.

A standard, C must be provided for attaeh- 1 ing the device to the machine upon which it is to be used, and the device is to be moved on the pin 0' by an arm, D, having one end connected to the depending ear D and the other end to some suitable cam or lever of the machine upon which it is to be used. The feed-rolls a a are geared together at one end, one gear only, a Fig. 3, bein shown. A ratchet-wheel, Z), is secured to the roll a and is actuated by two pawls, b, which are attached to the lever Z) and held in position by the double spring 19 The lever If has its bearing upon the stud b An adjustable stop, if, is supported on the pin C, and is held in position by the screw 1), which passes through the slot A spring, b serves to hold the lover 1)? down upon the stop-pin I). An arm or crank, c, is attached to the rolling cutter a, and a connecting-rod, c, connects the crank c with the adjustable quadrant c".

In operation the device has an oscillating motion about the pin 0 and in the direction of the dotted line y y. A roll of solder, E, of ribbon form and uniform thickness, is placed between the side plates, B B, and is held in place by a pin, E, passed loosely through its center and through the slots E in the side plates, B B. The roll of solder, E, rests its weight upon the ciu'rier-roll a, and the end of the ribbon passes between the feed-rolls a a As the device moves upward in the direction of the arrow the cutting-roll a is turned back by the connecting-rod c, leaving an opening between the knife 0 and the cutting edge of the cutting-roll of. At the same time the end of the lever 11 strikes the adjustable stip U, and causes a movement of the ratchet b, and consequently of the feed-rolls a? a The movement of the feed-rolls a (0 causes the solder to move forward as far as necessary between the cutting-edges of the knife o and the cutting-roll (L The amount of said forward movement is regulated by the adjustable stop 71''. As the device descends the spring b forces the lever Z1 back to its former positi on, and the solder is cut off by the return of the cutting-roll a. The port-ion of solder cut oli' drops through the opening a, which is made to coincide with the seam to be soldered.

The quadrant c may be set to cut the sol der at any desired position of the device.

I have described the device as moving in the direction of the dotted line y y upon the pin C, the standard C being stationary; but it is obvious that, if desired, the bed A could be stationary and the standard 0 used as a lever to operate.

hat- I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the bed-plate A, the sides B B, the knife a, the rolls a a a, the cutting-roll a and means for operating the movable parts, substantially as described, and for the purpose set forth.

2. The combi nation, with the bed-plate A,

the cutting-roll a, and means for operating to the sides B B, the knife (1, the rolls a a a the movable parts, of the crank c, the conthe cutting-roll a, and means for operating neeting-rod c, and the quadrant c substanthe movable parts, of the ratchet-wheel b, the tially as described, and for the purpose set 5 pawls I), the lever 5 and the adjustable stop forth.
